In parallel with this, the cassette tape 75 supported by the slider receiving plate 28, the cassette holder 21, etc.
The holding plate 35 is used to hold it down so that it is pushed down and stored at a predetermined position.

Next, a series of operations of the above-mentioned invention apparatus will be described. The structure of the cassette tape which is a target here is as described at the beginning, and when loading the cassette tape, first, the loading operation key (not shown) of the tape recorder is shown. Alternatively, a remote controller can be used) to start the drive device installed in the recorder, and the gear plate 64 rotates to start the operation of the insertion / removal mechanism. When the rotation direction at this time is defined by the direction of the solid line a, the pin 69 on the rack plate 66 fitted in the cam groove 65 of the gear plate 64 follows the rack plate 66 within the range permitted by the long hole 68. The pinion gear 60 ₁ that moves in the c direction and meshes with it by the rack portions 67 ₁ and 67 ₂ rotates in the clockwise direction and the gear 60 ₂ rotates in the counterclockwise direction, respectively, and the pinion gears 60 ₁ and 60 ₂ are coaxial. Each gear on top 6
Rotate 1 ₁ , 61 ₂ in the same direction as each pinion gear,
Side plate 2 _1, 2 ₂ Rack 3 ₁ is on, 3 ₂ and tray lever 1 e direction by engagement of, i.e. moved in the feeding direction is started.

At this time, the shift plate 54 is engaged with the gear plate 64 via the pin 59, but the cam groove on the upper surface of the gear plate 64 is
65 and the cam groove (not shown) provided on the lower surface are not the same, and therefore the shift plate 54 does not operate except at the time immediately before the end of the retracting operation of the tray lever 1, and only within the allowable range of the slot 58. It is kept in the state of moving forward, that is, in the state of FIGS. 2 and 3.

When the tray lever 1 is extended forward as shown in FIGS. 2 and 3, the swing frame 14 is rotated counterclockwise by the kick springs 17 ₁ and 17 ₂ and the cassette holder 21 is rotated by the kick spring 20.
It is rotated and suppressed clockwise by ₁ and 20 ₂ .
The front end of the cassette holder 21 is the contact member 7 of the front plate 4.
Since the slider receiving plate 28 and the cassette holder 21 are both in an inclined state as shown in FIG.
When the cassette tape 75 in the state shown in FIG. 12 (a) is mounted on the slider receiving plate 28 with the lid 76 inward (indicated by the dotted line), the cassette tape data hole is formed.
81 ₁ and 81 ₂ are positioning pins 2 on the cassette holder 21, respectively.
It fits into 2 ₁ and 22 ₂ for stability.

And the elasticity of the spring inserted in each connecting part is the cassette tape.
When it can withstand the weight of 75, it is slanted and is inserted while sliding in contact with the cassette restraining plate 35.However, if the elasticity of the spring is weak and the weight of the cassette tape is excessive, the holder 21 Since the cassette holder 21 is pivotally lowered, the fall of the cassette holder 21 at such a position becomes an obstacle to the pulling operation of the tray lever 1. Therefore, in order to prevent this,
The lowering stopper 8 ₁ of the cassette stopper 11 regulates the level of the cassette during the retracting operation.

When the pull-in operation key (not shown) of the tape recorder body is pushed in this state, the drive device starts reverse rotation, the gear plate 64 is rotated in the b direction, and the rack engaged with the gear plate 64 is rotated. The plate 66 is moved in the d direction, and accordingly, the pinion gear 60 _{1 and the} coaxial gear 61 ₁ are rotated counterclockwise, and the pinion gear 60 _{2 and the} coaxial gear 61 ₁ are rotated clockwise. Move.

Therefore, the racks 3 ₁ and 3 ₂ that are engaged with the gears 61 ₁ and 61 ₂ , respectively, start moving together with the side plates 2 ₁ and 2 ₂ of the tray lever 1 in the f direction, that is, the retracting direction. Also at this time, the shift plate 54 remains in the same state for a while.

And on the other hand, as shown in FIG.
The stopper protrusions 34 ₁ and 34 _{2 on} the innermost edge of the 28 contact the stoppers 48 ₁ and 48 ₂ protruding from the outer frame 74 to prevent the slider receiving plate 28 from further entering. Only 21 is moved further inward against the spring 27 within the permissible range of the respective sliding holes 23, 23 ₁ , 23 ₂ , and together with this, the cassette tape 75 also positions the positioning pin of the cassette holder 21.
The slider locks 79 ₁ and 79 _{2 on} the lower surface of the cassette tape 75 are pushed by the release projections 30 ₁ and 30 ₂ and are in the state where the slider 78 is unlocked while being held by 22 ₁ and 22 ₂ . Therefore, in the contact portions 80 ₁ and 80 ₂ of the slider end edges that are fitted in the notches 77 ₁ and 77 ₂ of the rit 76, the receiving claws 33 ₁ and 33 ₂ at the rear end edge of the slider receiving plate 28 are provided. Is pressed against the slider 78 to stop the movement of the slider 78, and the other portions are moved to relatively form a gap as shown in FIG. 12 (b) between the slider 78 and the slit 76. 76 doors can be opened.

And the last operation, that is, the end operation when the tray lever 1 is completely pulled in to the predetermined final position of the external frame,
Figure 5 to passively piece 8 of the cassette stoppers 11 attached to the rear surface of the front plate 4 of the tray lever 1 illustrated in FIG. 6 is in contact with release protrusion 47 on the outer frame 74 equivalents, falling stop piece 8 ₁
Is pushed clockwise against the elastic piece 9 with the screw shaft 12 as a starting point to release the locked state with the cassette holder 21, and the cassette holder 21 can be lowered (Fig. 8, (Fig. 9).

In this state, the cam grooves 65 correspond to the concentric arc portions, and the movement of the rack plate 66 stops. On the other hand, the cam grooves on the lower surface correspond to the non-concentric arc portions and the shift plate 54 to the gear plate 64. Although the operation is near the end, the tray lever 1 moves in the same direction as the retracting direction of the tray lever 1, that is, in the f direction for a very short time.

Thus, for shift arm 42 is engaged with the shift plate 54 in a downward projecting piece 43 _2, FIG. 10 as a starting point pivot portion to the outside frame 74, anti-as shown in FIG. 11 Rotate clockwise to move the cassette pressing plate 35 to the shift arm 42
And the shift arm 38 to move them substantially parallel to each other, and the upper surface of the cassette tape 75 supported on the cassette holder 21 and the slider receiving plate 28 is suppressed with an appropriate pressure so that the cassette is moved to a predetermined playable position. Insert the tape.

On the other hand at the same time, the downward projecting piece 43 ₂ of the shift arm 42 in conjunction with the operation of the suppression mechanism, outer frame 74
It acts on the pin 51 of the open lever 50 pivotally attached to the upper support piece 49 to rotate the lever 50 in the clockwise direction, so that the open arm 52 projecting to one side causes the lower edge of the cassette tape slot 76. When the cassette tape is lowered, the rit 76 is kicked up counterclockwise to be completely opened (FIG. 12c), thereby enabling play.

In this way, the cassette tape is inserted by the above series of operations, but the cassette tape is taken out from the tape recorder main body by the reverse procedure of the above operations.

That is, by pressing the take-out operation key, the gear plate
64 starts in the direction a, and in its initial operation, the operating direction of the shift plate 54 so far is switched to rotate and return the open lever 50 in the counterclockwise direction, while raising the cassette pressing plate 35, the cassette tape 75 At the same time, the lid 76 is automatically closed, and the gear plate 64 rotates to move the rack plate 66 in the c direction.
The tray lever 1 is fed out through 60 ₁ and 60 ₂ and gears 61 ₁ and 61 ₂ on the same axis.

The traveling operation, the cassette holder 21 slider receiving plate 28 by the elastic force of the tension spring 27 stopper 48 _1, 48 ₂
Since the slider is pressed toward, the movement of the slider receiving plate 28 is delayed by the length of the sliding hole, and when the cassette holder 21 moves within the allowable range of the sliding holes 23, 23 ₁ , 23 ₂ , the slider of the cassette tape. Reference numeral 78 denotes an internal spring which shifts the state of FIG. 12 (b) to the state of FIG. 12 (a) so that the cassette tape can be completely taken out before being loaded.

<Effects of the Invention> As described above, according to the present invention, the slider lever is slidably provided on the upper side of the cassette holder, the tension spring is tensioned between the two, and the tray holder is electrically retracted. With the tray lever, the tip of the slider receiving plate is stopped by a stopper on the external frame immediately before the tray lever is completely stored. Since the slider of the cassette tape is automatically moved by causing the slider to slide against the receiving plate, the slider attached to the cassette can be manually operated beforehand like the conventional cassette tape. Unlike loading the cassette tape after moving it with, the cassette tape can be loaded as it is without any prior operation. Since it is good, it is very easy to handle.

Further, the cassette tape is held by a cassette holder pivotally mounted on a tray lever that appears in and out of the external frame through a swing frame, and when the tray lever is pulled out from the external frame, the cassette holder is the upper edge of the tray lever. The cassette holding plate is configured to hold the cassette tape upper surface by pressing down and holding it at a predetermined position by lifting the tray lever and inserting the tray lever. Unlike guiding to the position, since it is guided by the two-stage swing motion of the swing frame and the cassette holder, the motion is much smoother than the sliding motion, and the deviation caused by wear and slight play is offset. It does not become difficult to operate due to things such as, and can perform light operation.

Further, since the position determining means of the cassette tape in the cassette holder is performed by the two positioning pins, the positioning is easy, reliable and stable unlike the conventional positioning of the cassette tape by the claw-shaped pieces. It has a remarkable effect such as.
